Oxygen Generators

Oxair offers a global service for the most cost-effective, efficient, more convenient and safest on-site sources for oxygen generators. We work with a range of industries, including the gold mining sector, hospitals, medical facilities, fish farming and other specialised areas.

Pressure Swing Adsorption (PSA)

We separate oxygen from Compressed Air through a unique process called Pressure Swing Adsorption (PSA). PSA is a unique process that separates oxygen from compressed air. The gas is then conditioned and filtered before being stored in a buffer tank and used directly by the end user on demand. PSA is recognised as one of the most popular methods for production of oxygen gas.

Oxygen Generators and their Industries

The technique and technology are suitable for small to medium size production supplies in various industries. The design of Oxair’s oxygen generators offers a reduction in power consumption when compared with other manufacturers. A fully reliable control system includes data collection with various outputs, communication links for remote control options and diagnostic analysis. Its proven design includes HMI Control with screen failure back-up.

The high cycle process valves are premier performers for reliability and low maintenance, especially robust in extreme environments. The process also has advanced noise control technology, resulting in an improved safety and environmental impact when compared with the competition.

Why choose Oxair?

The robust build, reliability and low maintenance are further qualities that also make our oxygen generators suitable for extreme environments, such as gold mining. Moreover, the specially designed muffler makes it one of the quietest PSA systems on the market.

Various other advantages are brought into play too when a constant, onsite source of oxygen is available, like mine-related industries. Not only are cyanide reactions affected but energy consumption can be reduced and the additional oxygen removes nitrogen entrainments present in the air.

Oxair’s oxygen generator can be engineered to integrate with any existing system, or designed from scratch. High purity oxygen is essential for the health and safety of patients and staff alike in medical facilities.  The Oxair system delivers constant oxygen of 95.5% purity through PSA filtration.

Our Oxygen Generators are capable of producing flow rates from 1 to 680 SM³/hr.

We can even provide on-site maintenance to keep everything running perfectly.
